    About the formats

    .opus

    Opus is a modern audio codec used by WhatsApp voice notes, Discord and WebRTC calls. It sounds great at low bitrates but many players and editors don't recognise .opus files.

    .m4a

    M4A is audio stored in an MP4 container, usually AAC. It's what iPhone voice memos, iTunes purchases and many recorders produce.
